A comparison of some indirect methods for predicting maximal oxygen uptake.
Nine male subjects took part in a comparative evaluation of four indirect tests commonly used for predicting maximum aerobic power (VO2 max). In three of these tests (involving cycling, stepping and walking) VO2 max was predicted from submaximal heart rates; in the fourth, VO2 max was predicted from the time taken to run 2 km. Additionally, VO2 max was predicted from the body fat content. All predicted values were compared with the VO2 max determined directly on a treadmill. The best estimates of VO2 max were provided by the timed run, and by the step test. Both heart rate measured during walking and body fat content proved totally inadequate for the reliable prediction of VO2 max. Taking into account such factors as cost, safety, and the time required for testing, it is concluded that the timed run is the submaximal test most suited to the indirect determination of VO2 max.
